# calcdate

calcdate is a utility to make some basic operation on date. It's useful when need to calculate a range of date in order to make database request.

```
Usage of calcdate:
-b string
Begin date (default "// ::")
-e string
End date
-i duration
Interval (Ex: 1m or 1h or 15s)
-ifmt string
Input Format (%YYYY/%MM/%DD %hh:%mm:%ss) (default "%YYYY/%MM/%DD %hh:%mm:%ss")
-ofmt string
Input Format (%YYYY/%MM/%DD %hh:%mm:%ss), use @ts for timestamp (default "%YYYY/%MM/%DD %hh:%mm:%ss")
-s string
Separator (default " ")
-tmpl string
Used only with -i option (default "{{ .BeginTime.Format \"%YYYY/%MM/%DD %hh:%mm:%ss\" }} - {{ .EndTime.Format \"%YYYY/%MM/%DD %hh:%mm:%ss\" }} {{ .BeginTime.Unix }} {{ .EndTime.Unix }}")
-tz string
Timezone (default "Local")
-v Get version
```

**Be careful, there is a breaking change after the version 0.5 (format is using % symbol).**

By default this is the current datetime that is printed.

```
$ ./calcdate
2020/09/14 23:15:10
```

# Some examples

```
$ ./calcdate -b //-1
2020/09/13 23:16:37
```

```
$ date && ./calcdate -b :-1: -e :-1:
lun. 14 sept. 2020 23:18:15 CEST
2020/09/14 23:17:00 2020/09/14 23:17:59
```

```
$ date && ./calcdate -b :-1:
lun. 14 sept. 2020 23:18:22 CEST
2020/09/14 23:17:22
```

```
$ date && ./calcdate -b :-1: -tz UTC
lun. 14 sept. 2020 23:19:08 CEST
2020/09/14 21:18:08
```

```
$ calcdate -b ":-5:" -e "::" -s "' and '"
2022/01/10 21:29:00' and '2022/12/31 23:59:59
```

```
date;calcdate -b ":-5:" -e "::59" -s "' and '"
lun. 10 janv. 2022 21:41:55 CET
2022/01/10 21:36:00' and '2022/01/10 21:41:59
```

In the below example, there is also a call to MinusOneSecond.

```
$ calcdate -b "2022/01/07 20:50:00" -e "2022/01/08 00:30:00" -i 5m -tmpl "{{ .BeginTime.Format \"%YYYY/%MM/%DD %hh:%mm:%ss\" }} - {{ .EndTime.Format \"%YYYY/%MM/%DD %hh:%mm:%ss\" }} {{ .BeginTime.Unix }} {{ .EndTime.Unix }} --- {{ (MinusOneSecond .EndTime).Format \" %hh:%mm:%ss \" }}"
